Key Features
- Routes traffic through the AWS global network instead of the public internet, reducing latency and improving availability.
- Automatically assigns two Anycast IP addresses for your application.
- Provides consistent performance regardless of client location.
How It Works
- Clients worldwide (e.g., in America, Europe, Australia) connect to the Anycast IPs.
- Traffic is routed to the nearest AWS Edge Location.
- From the edge location, traffic travels over the AWS private backbone directly to your application (e.g., a Public ALB in India).
Benefits
- Anycast routing ensures optimal path selection.
- Reduces hops and latency by avoiding the public internet.
- Delivers fast, reliable global access through AWS infrastructure.
- Works with both public and private application endpoints.
Supported Resources
- Elastic IP addresses
- EC2 instances
- Application Load Balancers (ALB)
- Network Load Balancers (NLB)
Consistent Performance
- Routes traffic intelligently to the lowest latency endpoint.
- Supports fast regional failover in under one minute.
- Avoids caching issues since the IP addresses remain static.
Health Checks
- Actively monitors the health of registered endpoints.
- Automatically fails over traffic if a target becomes unhealthy.
- Enables quick disaster recovery scenarios.
Security
- Only two external IPs need to be whitelisted for client access.
- Built-in DDoS protection through AWS Shield.
Addition:
AWS Global Accelerator is a networking service that helps you improve the availability and performance of the applications that you offer to your global users. AWS Global Accelerator is easy to set up, configure, and manage. It provides static IP addresses that provide a fixed entry point to your applications and eliminate the complexity of managing specific IP addresses for different AWS Regions and Availability Zones.
